This sophisticated water filter is produced using patented porous inorganic microfiltration filter technology. It is made of pure natural diatomite as raw material and sintered at high temperature. Combined with the new patented nano-metal filter material (Nano-KDF), its filtration accuracy reaches 0.1 micron. It can thoroughly filter suspended parasites, sediment and other pollutants in the water, effectively remove bacteria, algae, residual chlorine and harmful dissolved heavy metal ions (lead, cadmium, chromium, etc.
